-The upper side of the kick plate railll is capped by a glass-carryingrail 2l of. the type previously described, which fits over the flangesl2 of the rail 3|; and is held to the rail 30 by screws l5.

After the glass-carrying rails 2l Iare in place around the four sides ofthe light opening, the

glass 38 may be set-in place with its edges fitting over thechannelgrooves 24 and one side resting against the curved retainer 31which projects from one side of the glass-carrying strip 2|. Separateglass-retainer strips 38 of the shape shown' in Fig. 8 are then placedas shown in Fig.

As the result of the principles of construction used in this door allparts can be kept in stock machined to standard widths and thicknesses,subject to being cut to required lengths for the production of a door ofany desired size.

It will be clear to those skilled in the art that the frame may be madeof steel or any preferred strong material, and that the sheathingsections may be extruded or molded of any suitable metal or plastics.

If the sheathing sections are extruded from aluminum they may be given atreatment known as anodizing which gives the aluminum an attractive anddurable surface. The design is such that all of the aluminum parts'canbe anodized before final assembly. This is advantageous because analuminum product cannot be anodized after any metals or substances otherthan aluminum have been assembled with the aluminum.

I claim:

1. In a door of the type in which a frame is covered by a sheathing, theimprovement which comprises, a frame member, a unitary homogeneouslyintegral sheathing section having a substantially U`shaped cross sectiontted over the outer edge and sides of the frame member, and aglass-carrying cover strip interfitted with the edges of the sheathingsection.
